In an electrochemical water splitting, developing a cost-effective, abundant and highly efficient electrocatalyst is a major challenge for the large-scale production of hydrogen and oxygen gasses. Recently, applications of transition-metal based layered double hydroxides as electrocatalyst in water splitting have attracted attention because of their abundance, stability and environmental friendliness. Here, an ultrathin nickel-iron layered double hydroxide (NiFe-LDH) nanosheet was synthesized through electrodeposition on to nickel foam (NF) substrates. In alkaline solution, the as-synthesized ultrathin nanosheet has exhibited an excellent oxygen evolution activity. Combined with its lower overpotential of 240mV at 10mAcm-2 and turnover frequency at overpotential of 400mV, and durability over 15, 000 s, this material is a promising electrocatalyst for water splitting.
